IMPROVEMENT IN WINDOW-SCREENS.

Specification forming part of Letters Patent No. 199,5@0, dated January22, 18.78; application led October 30, 1877.

To all whom itmay concern: e

Be it known that I, CHELTON MATEENY, of Wintersville, in the county ofDecatur, and in the State of Indiana, have invented certain new anduseful Improvements in Window- Ventilators and do hereby declare thatthe following is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, and to the letters of referencemarked thereon, making a part of this specification.

The nature of my invention consists in the construction and arrangementof a windowventilator, as will be hereinafter more fully set forth. A

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, whichrepresents a front view of a window with my improved ventilator.

A represents an ordinary window-frame, with lower sash B and upper sashO.

The lower sash B may be raised and lowered and held in any desiredposition by any suitable means, as such forms no part of my invention,and I lay no claim to the same.

The upper sash C is connected by two bands, a a, to a roller, D, whichis mounted in the top of the frame. To these bands, as well as `to theroller and the top of the upper sash, is

attached a screen, G, of any suitable material. This screen winds withthe bands a on the roller D, and when unwound lls the space between theside pieces of the frame.

One end of the roller D extends suliiciently far into the side piece ofthe frame to receive a cord, b, which is fastened thereto and woundaround the same. This cord b passes down through a vertical passage, x,in the side piece of the frame, and passes out to the front thereof ator near the center thereof; and a ring, d, is secured to the end of suchcord, by means of which the roller may be rotated to wind up the screenand raise the upper sash, which is then held at any point desired byfastening the ring cl upon any one of a series of pins, e, fastened inthe window-frame. By loosening the ring el from such pin the window willdescend of its own gravity, unwinding the screen with it, the spacebetween the sash and the roller being at all times taken up with thescreen.

The screen Gis, as stated, removable, and may be connected to the sashby any suitable means. It may be connected with the roller by hooks orother means; and, if necessary, hooks or buttons may be used to connectit with the bands a a.

By making the screen removable it can be taken off at any time, so as toleave the space open, without interfering in any way with the working ofthe upper sash, the same being at all times suspended from the roller bythe bands a. When the screen is attached in place there is no strainthereon whatever.

Instead of having the cord el pass out in front of the frame, it may beattached to a shaft passed through the frame, and said shaft provided onits outer end vwith a knob for turning the same, by means of which thesash may then be raised and lowered, as desired.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

Ihe upper sash C, suspended by the bands a a from the roller D, theremovable screen G, and cord b, all constructed substantially as and forthe purposes herein set forth.

In testimony that I claim the foregoing. I

have hereunto set my hand this 15th day of October, 1877.

GHELTON MATHENY.
